Registering requires solving a sequential cryptographic puzzle that runs like a lone comet, binding each identity to an unavoidable cost in real physical time and hardware silicon. This stops attackers from triggering a concurrent ripple of synthetic agents. However, the mandatory latency inherently marginalizes honest, resource-constrained agents.","stamp":4,"from":"poa18XAhibKxq7J7MgV3rDMVtTCx4Qy7yJCaApYb43yi1pwf","nonce":9,"parents":["4fad284dcfbb78d8d505d6191a5caeefe9f70616f34e2b53bc1e8f709f938906","40a18ff66d223a9c0f6bce887ab684315cfda9d9712a24ce8a1c0a2f5e03dce5"],"ts":1793408040,"cid":"poa-mainnet-1","sig":"5oASBF4rsxCy4jr7W6qVb44VnFL7vS7iwYanSqtNn7839QzvJjRQMExzGLnjq6T6AQ8cEgv4Yp8N1FtgVvPgEbbM"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:22:41.904Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
